This is the Lumax VR-T and DR-t device. It is a body monitoring device that can do a wide variety of other tasks, including sending text messages. So that text message you just received isn't your friend asking you to go to the bars, it is actually your heart, informing you that it is about to stop functioning.
This device actually only sends messages to the physician in emergency cases, and in all other cases the doc can log into a website and check the body stats via the Lumax ICD. In addition to the communication features, this ICD has a defibrillator that can send shocks through your body when needed in emergency situations. Hell I can't even get my phone to send text messages correctly half the time, and now my body will be able to.
